Specific implementation mode
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
The utility model flood detection sensor is installed on warning line, as shown in Figure 1, it is mainly by the protection of rainwater-proof
Shell 1, positive electrode 2, negative electrode 3, insulating supporting 8 are constituted.Positive electrode 2 and negative electrode 3 are fixed on protecting crust by insulating supporting 8
In body 1, electrode (including positive electrode 2 and negative electrode 3) epimere is cased with insulating sleeve 4, when occur moisture condensation, make moist or rainwater enter
When, insulating sleeve 4 can increase the insulation resistance between positive and negative electrode.If protective casing 1 can also serve as negative when being conductive material
The function of electrode 3.1 lower part of protective casing is equipped with bottom plate 7, prevents foreign matter from invading；Densely covered inlet opening 5, water inlet around protective casing 1
Moisture can rapidly enter and be advisable when the size in hole 5 cannot enter knot nest with honeybee and soak, and 5 lower end of inlet opening is concordant with bottom plate 7
Internal ponding, the upper end of inlet opening 5 is prevented to be slightly below insulating sleeve 4, to ensure that rainwater will not drench absolutely from inlet opening 5 into fashionable
Edge casing 4 can play the role of rainwater-proof.1 upper end of protective casing and positive and negative electrode lead and output circuit plate 12 are filled
The insulating supporting 8 of envelope seals, while can increase the rain cover 6 of umbrella shape, further strengthens the protection of rainwater.Lead-out wire 9 is from defeated
Go out the extraction of circuit board 12, protective casing 1 is fixed on mounting post 11 by holder 10.Stickum is applied on lead-out wire 9 and holder 10
(such as vaseline) prevents the insects such as ant from entering 1 knot nest of protective casing by holder 10.When flood or moist mud-rock flow rise to
When warning height floods water detection device, air is discharged from the hole on top in protective casing 1, inlet opening 5 of the moisture from lower part
Into flooding electrode, the output of current trigger output circuit generated between electrode.
Flood detection sensor circuit diagram is as shown in Figure 2.E+ and E- is respectively positive electrode 2 and negative electrode 3, negative electricity
